This is a watermelon. It's been skinned, brined, smoked, basted, and grilled like a ham, so it resembles a ham. Duck's Eatery in New York City offers it as an entree, but you could make it at home, with some skill, particular ingredients and tools, and lots of time. What does it taste like? My guess is that it tastes like a watermelon, no matter what it looks like. My guess is also that it looks better than it tastes. -via Laughing Squid
